| This paper first analyzes the causes of torque ripple in four-wheel drive electric vehicles with brushless DC
motors. And then double sliding mode variable control system is designed to suppress torque ripple. Designing the double
sliding mode variable control system，the current error is selected as the sliding mode surface，so that the system moves
along the sliding mode surface. And designing the sliding mode observer detects the current generated in the commutation
process and feeds back the sliding mode control system to improve the stability of the system. The simulation results
show the double-sliding mode variable structure control system has better torque ripple rejection for the brushless
DC motor and stronger anti-interference ability. And it is able to be stronger anti-interference ability. Therefore，the brushless
DC motor with double sliding mode variable control system has better torque ripple suppression effect.
Keywords：four-wheel drive electric vehicles；brushless DC motors；double sliding mode variable control system |
